Since last year there is a smart authentication solution for all Rubik’s Cube lovers. This security solution is a Rubik’s Cube look-a-like (2x2x2) and designed by Cheng-Li Hung.

With this cube design you can create your own password by using your own color combination (you can even embed little pictures within each cube). You can take your security even a step further and make it a time based entry – solve the cube before time runs out and the colors change. The latter method is the best as otherwise brute-force attacks are possible. [Via JankoDesign]. Happy Puzzling!
